Disruption (and Recovery) of the ISP Business Model with IPv4 Depletion PTC12 15 January 2012 John Curran President and CEO, ARIN

Quick History of the Internet Protocol 2 Internet Protocol version 4 (IPv4, or just IP) – First developed for the original Internet (ARPANET) in spring 1978 – Deployed globally with growth of the Internet – Total of 4 billion IP addresses available – Well entrenched and used by every ISP and hosting company to connect customers to the Internet – Allocated based on documented need Internet Protocol version 6 (IPv6) – Design started in 1993 when IETF forecasts showed IPv4 depletion between 2010 and 2017 – Completed, tested, and available for production since 1999 – Total of 340,282,366,920,938,463,463,374,607,431,768,211,456 IP addresses available – Used and managed similar to IPv4

IPv4 Depletion Situation Report Each RIR received its last /8 from IANA on 3 February 2011. The IANA free pool of IPv4 addresses has reached 0%. While each RIR currently has IPv4 addresses to allocate, it is impossible to predict when each RIR will run out. ARIN publishes a daily inventory of available IPv4 addresses, at www.arin.net 4

IPv4 & IPv6 - The Bottom Line Were running out of IPv4 address space. IPv6 must be adopted for continued Internet growth. IPv6 is not backwards compatible with IPv4. We must maintain IPv4 and IPv6 simultaneously for many years. IPv6 deployment has begun. 5

6
RIRs have been allocating IPv6 address space since 1999. Thousands of organizations have received an IPv6 allocation to date. ARIN has IPv6 distribution policies for service providers, community networks, and end-user organizations. 6 IPv6 Deployment has begun

8
Your customers want access to the entire Internet, and this means IPv4 and IPv6 websites. Offering full access requires running IPv4/IPv6 transition services and is a significant engineering project. Multiple transition technologies are available, and each provider needs to make its own architectural decisions. 8 Broadband Changes

9
Content Changes Content must be reachable to newer Internet customers. Content served only via IPv4 will be accessed by IPv6 customers via transition solutions run by access providers. Plan on serving content via IPv6 in addition to IPv4 as soon as possible. 9

10
Mail, web, and application servers must be reachable via IPv6 in addition to IPv4. Open a dialogue with your Internet Service Provider about providing IPv6 services. Each organization must decide on timelines, and investment level will vary. 10 Enterprise Changes

11
Plan out how to connect businesses via IPv6-only and IPv4/IPv6 in addition to IPv4-only. Businesses are beginning to ask for IPv6 over their existing Internet connections and for their co-located servers. Communicate with your peers and vendors about IPv6, and confirm their timelines for production IPv6 services. 11 Internet Service Provider Changes
